Most rewarding area in pharmacy, expect in the NHS you get such a wide diverse variety of patients, where unfortunatley you do have to look at funding available for such high cost drugs. We also horizon scan, look at evidence base for new treatments too. NHS cancer treatment is world class where patients have access to fantastic treatments - not only in private care. We counsel patients on their drugs. Then theres paediatric haem/onc which is even more challenging but so rewarding. Best job ever!
